2000 Chevy S-10 severely need help with no start

I have fried my brain trying to figure it out for the last 3 days, while stranded in a tiny town.

Ok here it is , ignition no start. replaced ignition switch and key cylinder housing. reset and security light went off, started like a champ .. 2 times. back to a no start but this time when I turn ignition to the "on" position a relay clicks in a distribution block under dash. gauges light up everything works but no start. i have reverse lights so I did not believe it was the Positioning switch / neutral safety switch. Am I wrong?!?! I am about to lose my mind and job. Need serious help. Thank you in advance for any help you may offer.

* self edit

this is the relay that clicks when key is in "on " position. and clicks again when trying to start
the pic is side ways. but the left 5 prong relay. bottom in picture. has 2 brown, 1 dark blue, 1 red, and one thin black wire going to the back of it. starter test shows nothing

No more security light on !!
Check for power at the starter small wire
have a helper hold the ignition switch in start position
as you check for battery power at the small connector at the starter
If have power at good ground suspect bad starter
